Benefits of technology

The solution enables easy, instant connection and secure locking of cables, reduces assembly complexity, and provides effective strain relief, making it suitable for use in various applications, including narrow spaces and different cable sizes.

Problems solved by technology

However, this type of cable entry provides no locking of the cable to the cable entry.
However, assembling of such a cable entry is cumbersome, especially for an assembler, who might fit hundreds of cable entries each day.
Still another problem with the rubber cable entry is that it only fits material having a predetermined thickness.
There is a problem with the cable entry providing locking in that it comprises several constituent parts, have a space-consuming design and is cumbersome to assemble.
Also, when the cable is inserted into the cable entry and the cap is threaded to press the tongues towards the cable, the cable may not be completely locked, since the cable can slip in either direction if pulled, and the tongues may damage the coating of the cable.
Furthermore, although the cable entry is manually adjustable to surrounding material of different thickness, assembling of the cable entry using the nut may be cumbersome, especially if it is assembled in a narrow space.

Embodiment Construction

[0024]When a cable 1 is inserted into e.g. a cubicle, there are international standards for tightness classification, such as the IP classification system, that specify to what degree the internal atmosphere of e.g. a cubicle shall be sealed from the ambient atmosphere or fluid. Also, there are physical situations that require a cable 1 to be locked to a certain extent to the cubicle, to provide strain relief. A cable entry or locking grommet is provided for insertion into a hole of a material.

[0025]FIG. 1 illustrates a first embodiment of a cable entry device 100.

[0026]FIG. 2 illustrates the cable entry device 100 in cross-section with the cable 1 inserted into it. The cable entry comprises a core 110 enclosed by a covering 200, preferably made of an elastomer, adaptable to a surrounding material for sealing a space between the cable and the material.

[0027]FIG. 3 discloses a first embodiment of the core 110 according to the invention. The core 110 comprises an intermediate portion ...

Abstract

A core (110, 150) for supporting a covering (200, 510, 620) of a cable entry device (100, 500, 600). The core comprises at least one intermediate portion (111, 151a, 151b) connected to locking means (112, 113a, 113b, 152, 153a, 153b). The locking means are connected to the intermediate portion for instantly locking the core to a surrounding material when it is inserted into a hole thereof.

Description

TECHNICAL FIELD[0001]The present invention relates to a core for a cable entry device, and more particularly a core for locking the cable entry in a hole of a material, into which the cable entry is inserted.BACKGROUND OF THE INVENTION[0002]When a cable or conduit is inserted through a hole of a material, there are a number of methods available for protecting the cable against damage and sealing one side of the material from the other. If the cable is inserted into the interior atmosphere, of e.g. a cubicle, from the ambient atmosphere, a hole is made in the cubicle for inserting the cable.[0003]A rubber cable entry or grommet may be tightly inserted into the hole of the cubicle, and a cable can be inserted into the cable entry, causing sealing of the interior atmosphere of the cubicle from the surrounding atmosphere. However, this type of cable entry provides no locking of the cable to the cable entry. Also, it provides no locking of the cable entry to the surrounding material and ...
